Topic: Wooden Boat guys...WTF have I got here? Is it a model that I can RIDE!?? wooooo

[faux fiddy]

It is a displacement hull if you didn't know.  Not for speed. Any power over a horse or so will bury the transom, and cavitate.


Find or make a model steam engine for it, should be plenty of power.

[BeSeeingYou]

With that narrow beam it would not have the stability to ride on top...maybe not even inside.  Nice hull shape but not a clipper hull.  If I were to guess I'd say a whaling ship hull scale model.  Careful with a gas engine in there.  Gas engines in boats need modified carbs, spark arrestors, and ventilation.  Gas leaks or fumes in the bilge make boat go boom.  I would go electric.  Steam would be really cool too.

[dave500]

srust is right with the gasoline fume danger,my dad was in marine insurance for years,plenty of fume explosions,a few caused by the fans that were supposed to ventilate the area!

Steam would be cool, but expensive to do right, and I don't think you have enough room.  Steam setups need more open space than you have.

And while Dave and Srust are correct about fumes, you can do it safely.  Where it becomes an issue is when the engine compartment is closed up, and the fumes build up, and all it takes is an ignition source.  I'm not aware of carb mods, but marine engines have alternators and starters that are intrinsically safe.  It looks as if your engine has neither.  I can't tell from the pics, but it looks like either the engine hatch is missing, or there wasn't one in the first place.  But certainly one would have to be opened to start it up.  It also looks like exhaust and intake are not ported to the outside of the boat.  Exhaust must exit the compartment.  Probably a good idea to snorkle the intake air as well.

Let me know when you try to float it and I can bring my little cannon along to play sink the Frankenship. 

[Stev-o]

I christen thee "Deathtrap Frankenship"!

Oh Ye of little faith.

I like the "Frankenship" thing.

I've heard that people make a steam powered thing out of old lawnmowers. A firebox and boiler is tough, but down low it would make the ballast.

I would think that's about a 7 knot boat in flat water.

[scottly]

  I would go electric. 

1+ I put a permanent magnet motor robbed from an electric scooter on a minibike. I paid something like $50 for the scooter, with the batteries, motor, and 30 amp/24 V controller.

If you do gasoline, make it where you can pilot and  detonate it by remote.  And save a video for you tube.

You can calculate the speed of a displacement hull using the formula 1.34 x square root of the waterline length.  Let's just say it's 7 feet so it works out to roughly 3.5 knots (1.34 x 2.64).  It has to do with the wave created by the bow.  As this type of hull reaches it's speed potential the bow wave cycle lengthens to equal the waterline length and the boat sits in a hole created by the bow and stern wave.  It can now move along efficiently supported at the bow and stern by their respective waves but to go faster it has to climb out of this hole and it takes a disproportionate amount of power for a small gain in speed.  There are also formulas for matching prop pitch and diameter, RPM and HP.  It's like science for boats.

You know the math behind  it more than I do, but boats-r-fun.

I had this scow, out of chappelle design.  As much as I was told that no one in Icy Straight is going to check a fishing license, I was boarded (sotr of ) on my second voyage.  i saw them making a beeline out of cross sound. More to this story and others>

Anyway, it was built in '58 I'm told.  It was a sein skiff, fitted with a tabernacle and sail somewhere between now and then, I left it on the beach when I took my 'opportunity' with the state.  The boat might still be there, but our senator was indicted on my suggestion to the court.

Go figure. Employment can cause some unnecessesary yanks because of  the yanks. Sorry if any canuks felt I said anything offensive like buster body crab being canuk, as  I know first hand, the real dirtbags are west of BC, stealing intercepting providing treaty information as many salmon   on as many as they can  take. 

Maybe I can rephrase that where it's not censored.

[faux fiddy]

Hey Frankie, you've brought me to somewhere I haven't been in too long.

Here is the boat, easy enough to build. A 10 hp honda is overpowered. Leeboards for sailing. I think this was fitted with a tabernackle and sails  in the '70's.   It might have had  fishing permits. I abandoned it.   It was homemaid in hanes, but you can build them easy , chapell design.

 Weird tide made the GPS say we were doing 11 kts one time across Glacier Bay.  Guy in the pic is who I got it from.

Sucks to see things I lost posted. maybe it's still there.... and only needs a few planks , more pics here?

[faux fiddy]

Oh yeah, one time I was between there and that place you see, Lemisure Island in March. After dragging anchor overnight Was delivered to the speck on the horizon.  and I sailed tacking  in  on offshore North wind nobody there but me.  The  I think my reaction to the blast of wind was proper, pullung the keel and riding it out, but at that point in time I never felt so alone in my life.
It came back up.

I was sure I woud capsize.

I told the PO about it, and his question was did the sail hit the water?  I said "no." He said "now you know."   Flat bottom  and a skag beaches well, tumble home sides make it find it's way down.  You can find a Chappelle book. 10 HP honda is perfect / overkill at WOT.  I used it to sail back in.

Pulling the keel up probably allowed the boat to slip sideways and not "trip" over the leeboard(keel).  Got some stories to tell?   Me...have more boats than bikes.

[faux fiddy]

I used to go out and fall asleep with the anchor down and a line with fresh bait.  I could get real close to shore or in a channel, usually I'd look for a dip or hump on the depth finder  then take a nap. There was a non pc name for that sort of fishing.

Sometimes the clicker on the Penn would wake me up on my day off. Usually only 30 lb. halibut. Perfect for a batchelor without any freezer. (Or electricity for that matter!)  Always had frends that would freezer store a little bit, but not moose quantities.  I had to pack someone else's kill out of the swamp for my moose meat  shares.

[faux fiddy]

Oh, I meant rudder, not keel. It was a surf board of a boat. Had a skag  and a big rudder.

Supposed to do well in any following seas.

[faux fiddy]

It is liike a dutch river barge. I hear there is a big one in the SF marine museum. Same basic design.

[demon78]

When I was a kid I came down with rheumatic fever and spent a couple of years in bed, so my parent got me "Shipping Wonders of the World" published in 1936 2 volumes and because I had nothing to do but read I went through both volumes repeatedly and if I had them now I'd be able to pull up the exact match It could be a model of any number of low country boats/ships or English river and coastal designs, small working boats that everyone used before the advent of cheap diesel power. I don't know if it is worth pursuing but you also might find hulls like that at the Portuguese maritime museum in Peniche they have hull designs and progressions there Also I can't remember but didn't SamCR750a say he was in the RN, he might be able to direct you to the right spot.

Sorry 'bout the threadjacking...

I found several pictures google scow +  SF Maritime Museum., I guess in the days of horse and buggy they were the fuel barges for the bay area.





Chapelle  was the guy that went around to all the rotting boatyards and drew diagrams of all the wooden boats before they rotted away.   Most large libraries have a book or two of his.

Here's a thread on building a model, and where to get diagrams.

You mean half a model.  The guy gave up in '08 because he didn't like planking it.  At least he said so at the bottom of the page, instead of just fading away.  I happen to be in the middle of planking a model boat myself.  Nothing as grand as that, but I'm proud of it.



This is a pic of just two planks in place, but it currently has about 10.  Hopefully more by the end of the day.  Can we get back to Frankenship now?

[Mtmooradian]

I'd say 150hp will work

[Stev-o]

Yeah, a 150 Merc on the Franknship!
